Abstract 

Loss of seagrasses has been documented worldwide and has been correlated with 

anthropogenic eutrophication and alteration of habitats. Developing a seagrass restoration 

target or numeric goal based on available understanding of the history and physical 

characteristics of an estuary sets up guidelines for ongoing and future habitat restoration 

projects. Palm Beach County (Florida) Department of Environmental Resources 

Management has developed a methodology to model a seagrass restoration target in Lake 

Worth Lagoon. Potential sea grass habitat is modeled using a bathymetric survey to 

develop a digital elevation model, seagrass mapping from aerial photography to 

determine seagrass distribution by depth, and estuarine substrate characteristics. A user 

can determine where seagrass restoration or recruitment is likely to occur and can assist 

in setting a restoration target based on these factors. Additionally, the information 

developed provides an effective management tool to determine where restorative and 

protection efforts should be focused. 

Summary 

The objectives of this paper are to: (1) discuss existing information used for the 

development of a seagrass restoration target for the Lake Worth Lagoon (LWL), (2) 

discuss the methodology to model a seagrass restoration target in LWL; and (3) discuss 

potential seagrass restoration targets for the three segments of the lagoon. 

LWL has realized significant losses of seagrass over time due to water quality impacts, 

dredging, and urbanization. Seagrass loss and their retreat to shallow water have been 

attributed to a reduction of available light which is confirmatory of the poor water quality 

in the lagoon. Mandate for the protection of seagrass comes from several sources 

including the 1998 LWL Management Plan, Palm Beach County Comprehensive Plan – 

Coastal Management Element, Florida Statute 376.121 - Liability for Damage to Natural 

Resources, and the Federal Endangered Species Act protecting listed species of seagrass. 

Historical seagrass surveys from 1940, 1975, 1990 and 2001, and predictive modeling are 

presented in this report to provide a benchmark for the development of the seagrass 

restoration model. 

 

Seagrass restoration target depths for each lagoon segment at which adequate depth, light, 

and substrate conditions to ensure seagrass growth and future recruitment were identified. 

Based on the GIS modeling conducted, a possible LWL seagrass restoration target is 

2,0921

 acres based on best available information and understanding of the estuarine 

system. The possible target is based on 2001 seagrass distribution data and modeling of 

potential seagrass habitat which includes adequate depth and substrate. This target may 

be achieved over a 20 year period through the management of nutrient and sediment 

loadings, removal of muck sediments in the lagoon, and diversion of freshwater

discharges. Developing a seagrass restoration target or numeric goal based on available 

understanding of the history and physical characteristics of an estuary sets up guidelines 

for ongoing and future habitat restoration projects. 

LWL is located on the eastern shore of South Florida in Palm Beach County (Figure 1) 

and is approximately 20 miles in length, 1⁄2 mile wide with average depth of 6 feet. It is 

estimated that current seagrass coverage is 1,626 acres based on an aerial assessment of 

2001 conditions. The LWL is divided into three segments (north, central, and south) 

based on hydrological factors including water quality, circulation, and physical 

characteristics

Seagrass Background and Current Status 

Seagrass beds are highly productive and ecologically important habitats within South 

Florida's estuaries and coastal lagoons. The combination of plentiful shelter and food 

results in seagrass beds being perhaps the richest nursery and feeding grounds in South 

Florida's coastal waters. Seagrass beds are nursery grounds for the juveniles of a variety 

of finfish and shellfish of commercial and recreational fishing value. The roots and 

rhizomes stabilize the sediments, promote sedimentation of particles, inhibit resuspension 

of sediments, and maintain an active environment for nutrient recycling. The seagrass 

blades provide a substrate on which epiphytes can attach, providing a more valuable food 

source to most consumers. Seagrasses probably are more important to the food web as 

detritus than as a source for direct herbivory. Detritus is an important food source for 

deposit feeders, providing polychaetes, amphipods, isopods, ophiuroids, some 

gastropods, and mullet with much of their nutrition. Seagrasses are also important 

because they are the primary food source for the Florida manatee (Palm Beach County 

Environmental Resources Management (ERM) & FDEP 1998). 

Losses of seagrasses have been documented worldwide and have been correlated with 

anthropogenic eutrophication and alteration of shorelines and habitats. Declines, as 

seagrass beds typically retreat to shallow depth, have been correlated with a reduction in 

available light due to an increase in phytoplankton, epiphytic or macroalgal growth 

(Bortone 2000). The LWL Management Plan recognizes the importance of this resource 

and the factors responsible for the decline of seagrass and has addressed it through the 

goal of attaining and maintaining water quality and sediment quality of sufficient quality 

to sustain a healthy estuarine ecosystem. 

The most recent assessment of seagrass coverage was conducted in 2001. Results of the 

2001 seagrass mapping project using aerial imagery demonstrate that seagrass beds cover 

at least 1,626 acres or approximately 22% of the lagoon (Baymont 2001). Additional 

seagrass was present; however, the lack of water clarity prevented mapping of all 

seagrass beds. The coverage varies throughout the three segments of the lagoon. 

Specifically, 69.7% of the seagrass in LWL are in the northern segment of the lagoon, 

11.8% of the seagrass are in the central segment of the lagoon, and 18.5% of the seagrass 

are in the southern segment of the lagoon. The overall seagrass coverage within each of 

the segments is 33.5% in the north, 9% in the central, and 17% in the south segment of 

the lagoon.

Methodology for Developing a Model 

Step 1: Assembling Data Sets and Base Analysis 

The first step in developing the model is to assemble existing data sets and determine the 

distribution of seagrass by depth using seagrass coverage and bathymetry data. Figure 2 

presents the intersection of bathymetry point data and seagrass data in a selected area of 

LWL. 

Figure 2. Intersection of Bathymetry Transect Data and Seagrass Data for Determination 

of Seagrass Distribution by Depth. 

 

Approximately 92% of the seagrass in the north segment is present at depths of -2.0 to 

-6.0 feet NGVD. The average depth of seagrass in the north segment is -5.0 feet NGVD.

The central segment of LWL is the most severely impacted segment of the lagoon with 

respect to water quality and the presence of muck. The central segment is currently listed 

on the FDEP Verified List of Impaired Waters. As water quality and light attenuation 

decrease, seagrasses have been known to retreat to shallow depths (Bortone 2000). The 

central segment of the Lagoon typifies this phenomenon. In a striking contrast to the 

north segment, there are only 192 acres (9% coverage) of seagrass in the central segment. 

The majority of seagrass is only found at depths between -3.0 to -5.0 feet NGVD. The 

average depth of seagrass in the central segment is -4.4 feet NGVD. Figure 4 presents the 

distribution of existing seagrass in the central segment.

The south segment of LWL is also stressed due to poor water quality and is typified by 

the retreat of seagrass to shallow depths where light requirements can be met. Presently, 

there are only 300 acres (17% coverage) of seagrass in this segment. The majority of 

seagrass is only found at depths between -3.0 to -4.0 feet NGVD. The average depth of 

seagrass in the south segment is only -3.4 feet NGVD. Figure 5 presents the distribution 

of existing seagrass in the south segment.

Step 2: Digital Elevation Model 

The second step is to generate bathymetry for the entire LWL based on a bathymetry 

transects performed in 2003 (Morgan & Eklund). Using 3D Analyst, the bathymetry data 

is interpolated to a raster data set using the inverse distance weighted (IDW) interpolation 

technique. This technique is used to determine cell values using a linearly weighted 

combination of a set of sample points. The rasterized data set is reclassified as necessary 

for ease of analysis of other factors. Now that a digital elevation model for the LWL has 

been created, analysis based on depth can be achieved for a variety of factors. For 

example, different seagrass recruitment scenarios may be set up based on depths at which 

seagrass is likely or targeted to recruit. Other ecosystem component models may be 

developed for other benthic organisms using this approach (e.g., American oyster). 

Step 3: Modeling Substrate 

While seagrass recruitment is dependent upon a complex set of factors and dynamics, 

there are basic building blocks which are important to the colonization of seagrass. One 

of the building blocks is suitable substrate. For this exercise, substrate characteristics 

were modeled for LWL because a substrate map had not been previously developed. 

Historical data from the late 1960’s collected by the U.S. Environmental Protection 

Agency was digitized and combined with a muck survey performed during the 2003 

bathymetric data collection event. In this case, muck deposits greater than 1 foot were 

mapped principally in the central and southern segments of LWL using a dual frequency 

fathometer. These data sets were integrated into a single shapefile. Once integrated, a 

Triangulated Irregular Network (TIN) was created to interpolate unmapped areas of the 

LWL. The TIN was then converted to raster and reclassified. Figure 6 presents the raw 

data and reclassified substrate map.

and Substrate Contour Map (B) 

 

In the same manner that seagrass distribution by depth is analyzed, seagrass distribution 

by substrate is developed. Figure 7 presents seagrass distribution within LWL by 

substrate.

Figure 8 presents LWL 2001 seagrass data distribution by modeled substrate 

characteristics. An analysis of the results indicate that seagrass is predominantly found in 

sandy environments and does not colonize well in silty environments. However, further 

analysis of the results demonstrates that seagrass is colonizing silty environments within 

the central and southern segments of LWL. These seagrass beds, found in impacted areas 

of LWL are not typical of healthy beds. Although seagrass may be found in these 

environments, seagrass is not expected to successfully recruit in areas with high silt 

content.

Step 4: Developing the Target 

Several factors were analyzed to determine a possible target for seagrass restoration. 

These involve using a historical seagrass model, earlier seagrass mapping studies, and the 

use of current seagrass distribution, and substrate characteristics to predict future 

recruitment. 

The earliest seagrass survey for LWL was performed in 1940 (Palm Beach County ERM 

& Florida DEP 1998) and found that 4,271 acres of seagrass were present. An analysis 

performed for this study using current seagrass distribution data confirmed the results of 

the 1940 study. The comparison was developed based on the premise that given pristine 

water quality conditions in the lagoon and ideal depth at which light penetration allows 

for the growth of seagrass, a prediction can be made as to the total distribution of 

seagrass in an arbitrary year (e.g., 1940). Assuming that seagrass would be present at -

9.0 feet NGVD, the total amount of seagrass is predicted at 4,440 acres. The prediction is 

within 4% of that surveyed in 1940. It should be noted that areas of the lagoon have been 

deepened since 1940 and this has not been accounted for in the current study. 

In 1975, a resource inventory was performed and found that only 161 acres of seagrass 

remained in LWL, representing a substantial loss of seagrass from 1940. The loss of 

seagrass was hypothesized to be linked to sewage disposal outfalls that directly 

discharged to LWL as well as degraded water quality. This was inevitable due to the 

rapidly expanding population surrounding the estuary and the technology associated with 

wastewater treatment plants. During the 1950s, an estimated ten million gallons per day 

(MGD) of raw sewage was discharged to LWL resulting in extensive bacterial and 

nutrient pollution. By 1970, seven major waste water treatment plants had been 

constructed, discharging 18.49 MGD of secondarily treated sewage effluent. The volume 

was reduced to 2.98 MGD by 1984, largely as a result of the NPDES program 

administered by the USEPA (Palm Beach County ERM & Florida DEP 1998). Today 

there are only two small “package” wastewater treatment plants discharging into LWL. 

In 1990, a natural resource inventory was performed on LWL (Dames & Moore) and 

included detailed in-water surveys which provided the most complete information to date. 

The survey indicated that there were 2,110 acres of seagrass; approximately half of the 

amount of seagrass in 1940. However, there was an increase of 1,945 acres when 

compared to results of the 1975 survey. It should be noted that the surveys used 

markedly different methodologies and the preceding discussion is designed to illustrate 

magnitude of change. 

In 2001, true color aerial photographs were interpreted to determine the seagrass 

coverage in LWL. While this did not include extensive in-water ground truthing, the goal 

was to develop a method to be used for a baseline for future studies. The north segment 

was determined to have the majority of seagrass, 1,134 acres followed by the south 

segment with 300 acres; and the central segment with 192 acres of seagrass. The total 

coverage was determined to be 1,626 acres of seagrass. Although the methods of 

analysis were markedly different for the 1990 and 2001 surveys, there appears to be a 

loss of seagrass coverage over an 11-year period. One possible explanation for the loss 

during the 1990’s is that development increased rapidly in the watershed causing upland 

disturbance and increased stormwater discharge. This development led to increased 
9

eutrophication and release of sediments into the lagoon which supported by water quality 

data for the time period. Table 2 presents a summary of seagrass coverage in LWL from 

1940 through 2001.

Arbitrary date reflects conditions prior to intense urbanization; conditions allow for maximum coverage of 

seagrass.

4,440 acres is the maximum of seagrass given pre-WWII conditions under these model assumptions. 3

Due to gross differences in survey methods, these values should only be used to indicate an order of 

magnitude change. 

Target Development 

To establish a seagrass restoration target for LWL, a benchmark time period is needed. 

Although the 1940 seagrass beds were modeled, there have been significant changes in 

shoreline and many areas that have been dredged and filled since the 1940’s. Overlaying 

the 1990 or 2001 seagrass maps over the 1940 coverage to determine restorable areas has 

limitations given the above changes to the system. Likewise, overlaying the 2001 maps 

over the 1990 map is also problematic due to the difference with which the surveys were 

conducted. Therefore, it is recommended that the 2001 seagrass survey be used as the 

benchmark time period supplemented by predictive modeling. 

One goal of the management plan is to halt the loss of current seagrass beds in LWL. A 

second goal is to restore seagrass to an historic and achievable level given the effects of a 

highly urbanized estuary and the effects of rapid population growth in Palm Beach 

County. A compromise needs to be achieved between the 1940 coverage of 4,271 acres 

and the 2001 coverage of 1,626 acres of seagrass. A third goal not explored in this paper 

is to preserve existing seagrass beds with a focus on preserving high-density beds. 

Rather than choosing an arbitrary date as a restoration target which may be unachievable 

in the long run, it may be reasonable to expect incremental improvements in water quality 

which in turn will allow more light to penetrate the water column. This small 

improvement in light attenuation will provide the environment for the restoration of 

seagrass throughout LWL. 

Utilizing historical data is not without problems due to changes in technology and survey 

method differences. Therefore, using current seagrass distribution to predict future 

seagrass distribution along with examining historical trends should result in setting a 

suitable target for seagrass restoration. As presented earlier, analyzing 2001 seagrass 

distribution in concert with 2003 bathymetric data for LWL results in establishing 

seagrass distribution by depth (See figures 2-4). The average seagrass depth for each 

LWL segment was computed using seagrass distribution and bathymetric data. Setting a 
10

target depth assumes that there should be at least a small improvement in water quality 

that would allow for increased light attenuation through the water column. Using a very 

conservative approach of increasing the average seagrass depth by one foot in the north 

segment and 0.6 feet in the central and south segments, respectively, leads to the target 

depths as presented in Table 3.

Predicting where seagrass is likely to recruit based on depth and suitable substrate 

provides a more realistic target. Figure 9 presents a snapshot of where seagrass is 

predicted to recruit in conjunction with suitable sediment characteristics within 5 feet of 

the surface. 

Figure 9. Snapshot of Suitable Depth and Substrate for Seagrass Recruitment 

 

In summary, it is recommended to use seagrass depth distribution data and substrate data 

to develop segment specific seagrass target depths, expressed as NGVD. Potential target 

depths are: -6.0 feet for the north segment, -5.0 feet for the central segment, and -4.0 feet 

for the south segment. These targets will allow for the protection of the existing 1,626 

acres and the restoration of 466 acres of seagrass. Table 4 presents the current 

distribution of seagrass in LWL as well as the restoration target for seagrass in each of

the three segments. The potential seagrass recruitment target is the sum of existing 

seagrass plus potential seagrass recruitment as predicted by both depth and substrate.

It is evident from Table 4 that the greatest potential for seagrass recruitment is in the 

Central segment of LWL. There are extensive, relatively shallow areas that currently are 

not colonized by seagrass. Therefore, it would appear that efforts should be directed 

toward water quality and sediment management in this portion of the lagoon. A map of 

LWL with the target developed for this model is presented in the Appendix. 

Achieving the Target 

The LWL seagrass restoration goal will be accomplished when the deep edges of the 

seagrass eventually extend to, delineated by high-resolution aerial photography, the target 

depths and substrate delineation set for each segment. Protection of existing coverage 

and the restoration of an additional 466 acres (based on model results) of seagrass may be 

accomplished through management of external nutrient and sediment loadings as well as 

the removal of muck sediments in the central segment of LWL. A possible timeframe for 

the proposed restoration target is 20 years. These goals are outlined in the LWL 

Management Plan and are currently being implemented. For example, the LWL 

Partnership Grant Program has received $12,800,000 from the Florida State Legislature 

since 1999. A total of 37 construction projects have been funded as well as baseline 

monitoring projects. The following projects have been implemented to initiate the 

restoration of seagrass: 

• 17 stormwater projects treating more 1,200 acres of runoff; 

• 11 habitat enhancement projects creating new and restored habitat; 

• 3 sewage treatment projects; and 

• 7 baseline studies assessing the health of LWL 

Additionally, PBC ERM has proactively embarked on many restoration and enhancement 

projects (Munyon Island, Peanut Island, Snook Islands, John’s Island, and many 

mangrove planter projects) to increase habitat in LWL. 

The Comprehensive Everglades Restoration Plan (CERP) is addressing water quality, 

sediments, muck deposits and habitat in LWL through the Northern Estuaries Module. 

Additionally, the Palm Beach County Comprehensive Plan – Coastal Management 

Element addresses improving water quality in estuarine environments.

End Notes 

There are several limitations and uncertainties associated with the possible restoration 

target. The target is based on a 2001 aerial interpretation of seagrass which mapped 

seagrass beds of 0.25 acres or larger. The proposed target assumes that depth, light 

penetration, and substrate are the major factors affecting seagrass recruitment. Further 

study is recommended on assessing sediment characteristics of the lagoon and potential 

seagrass recruitment. Additionally, this study does not take into account annual 

variations, effects of natural events (e.g., weather events), diversion projects affecting the 

lagoon (e.g., C-51 canal diversion), or water quality of contributing basins to the LWL 

watershed. The possible seagrass restoration target discussed in this paper was developed 

to foster support for improved conditions in LWL. The methodology and target are 

currently under review and have not been adopted by the LWL Program or PBC ERM.
